1 Introduction
1.1 System Introduction
E8KT/E10KT/E12KT can be applied in DC- coupled systems (mostly new installation), AC-
coupled systems (mostly retrofit) and Hybrid-coupled systems (mostly retrofit, and PV
capacity-increase), as the following schemes show:
Figure1 DC-coupled Storage System-Scheme
Figure 2 AC-coupled Storage System-Scheme

6
Figure 3 Hybrid-coupled Storage System-Scheme
1.2 Operation Modes
There are three basic modes that end users can choose via inverter screen/APP.
SELF CONSUME: The energy generated by the solar panels will be used in the following
order: Feed the home loads; Charge the battery and then, feed into the grid.
When the sun is off, the load will be supported by battery to enhance self-consumption.
If the power supply from the batteries is not sufficient, the grid will support the load
demand.
BAT PRIORITY: Under this mode, the battery is only used as a backup power supply
when the grid fails and as long as the grid works, the batteries won’t be used to power
the loads. The battery will get charged with the power generated by the PV system or from
the grid.

7
PEAK SHIFT: This mode is designed for time-use mode customer. The customer is able
to set up the charging/discharging time & power via inverter screen or APP.
1.3 Safety Introduction

personnel and property. This manual should be kept carefully for maintenance and
reparation.
1.3.2 Operator Requirements
The operators should get a professional qualification, or be trained.
The operators should be familiar with the whole storage system, including compositions
and working principles of the system.
The operators should be familiar with the Product Instruction.

8
While maintaining, the maintainer is not allowed to operate any equipment until all the
equipment has been turned off and fully discharged.
1.3.3 Protection of Warning Sign
The warning signs contain important information for the system to operate safely, andit
is strictly prohibited to torn or damage them. Ensure that the warning signs arealways
well-functioned and correct placed. The signs must be replaced immediatelywhen
damaged.
This sign indicates a hazardous situation which, if not avoided,
could result in death or serious injury!
The E8KT/E10KT/E12KT must not be touched or put into
service until 5 minutes after it has been switched off or
disconnected to prevent an electric shock or injury.
This sign shows danger of hot surface!
Refer to the operating instructions.
1.3.4. Setting of Warning Sign for Safety
During instruction, maintenance and repair, follow the instructions below to prevent
non-specialist personnel from causing misuse oraccident:
Obvious signs should be placed at front switch and rear-level switch to prevent
accidents caused by false switching.
Warning signs or tapes should be set near operatingareas.
The system must be reinstalled after maintenance oroperation.
1.3.5. Measuring Equipment
To ensure the electrical parameters to match requirements, related measuring equipment
are required when the system is being connected or tested. Ensure that the connection
and use matched specification to prevent electric arcs or shocks.
1.3.6. Moisture Protection
It is very likely that moisture may cause damages to the system. Repair or maintaining
activities in wet weather should be avoided orlimited.
1.3.7. Operation after Power Failure
The battery system is part of the energy storage system which stores life-threatening high
voltage even when the DC side is switched off. Touching the battery outlets is strictly
prohibited. The inverter can keep a life-threatening voltage even after disconnecting itfrom
the DC and / or AC side. Therefore, for safety reasons, it must be tested with aproperly
calibrated voltage tester before an installer works on the equipment.

1.5 General Precautions
DANGER
Danger to life due to high voltages of the PV array, battery and electric shock. When
exposed to sunlight, the PV array generates dangerous DC voltage which will be present
in the DC conductors and the live components of the inverter. Touching the DC
conductors or the live components can lead to lethal electric shocks. If you disconnect the
DC connectors from the system under load, an electric arc may occur leading to electric
shock and burns.
Do not touch uninsulated cable ends.
Do not touch the DCconductors.
Do not open the inverter andbattery.
Do not wipe the system with dampcloth.
Have the system installed and commissioned by qualified people with the
appropriate skills only.
Prior to performing any work on the inverter or the battery pack, disconnect
the inverter from all voltage sources as described in this document.
WARNING
Risk of chemical burns from electrolyte or toxic gases. During standard operation, no
electrolyte shall leak from the battery pack and no toxic gases shall form. Despite careful
construction, if the Battery Pack is damaged or a fault occurs, it is possible that electrolyte
may be leaked or toxic gases formed.
Do not install the system in any environment of temperature below -25°C
or over 60°C and in which humidity is over 95%.

11
Do not touch the system with wethands.
Do not put any heavy objects on top of thesystem.
Do not damage the system with sharp objects.
Do not install or operate the system in potentially explosive
atmospheres orareas of high humidity.
Do not mount the inverter and the battery pack in areas containing highly
flammable materials or gases.
If moisture has penetrated the system (e.g. due to a damaged enclosure),
do not install or operate the system.
Do not move the system when it is already connected with battery
modules.Secure the system to prevent tipping with restraining straps in
yourvehicle.
The transportation of E8KT/E10KT/E12KT must be made by the
manufacturer or an instructed personal. These instructions shall be recorded
and repeated.
A certified ABC fire extinguisher with minimum capacity of 2kg must be
carried along when transporting.
It is totally prohibited to smoke in the vehicle as well as close to the vehicle
when loading and unloading.
For the exchange of a battery module, please request for new hazardous
goodspackaging if needed, pack it and let it be picked up by the suppliers.
In case of contact with electrolyte, rinse the affected areas immediately
withwater and consult a doctor without delay.
